Graphene yog exfoliated los ntawm flake graphite khoom, ib tug ob-seem siv lead ua los ntawm carbon atoms uas yog tsuas yog ib tug atomic tuab. Vim nws zoo heev optical, hluav taws xob thiab mechanical zog, graphene muaj ntau yam kev siv. Yog li flake graphite thiab graphene yog muaj feem xyuam? Tus Furuite graphite editor hauv qab no tshuaj xyuas kev sib raug zoo ntawmgraphite flakethiab graphene:
1. Txoj kev rho tawm ntawm graphene pawg ntau lawm tsis yog feem ntau tau los ntawm flake graphite, tab sis los ntawm cov pa roj carbon xws li methane thiab acetylene. Txawm hais tias lub npe muaj lo lus graphite, kev tsim cov graphene tsis yog feem ntau tau los ntawm flake graphite. Hloov chaw, nws tau los ntawm cov pa roj carbon xws li methane thiab acetylene. Txawm tias txoj kev tshawb fawb tam sim no yog rho tawm los ntawm cov nroj tsuag loj hlob, thiab tam sim no muaj ib txoj kev rho tawm graphene los ntawm cov ntoo tshuaj yej.
2. Cov graphite flakes muaj ntau lab graphene. Graphene yeej muaj nyob rau hauv xwm. Yog tias muaj kev sib raug zoo ntawm graphene thiab flake graphite, ces graphene yog superimposed txheej los ntawm txheej los tsim graphite flakes. Graphene yog ib qho me me heev ib txheej qauv. Lawv hais tias ib millimeter ntawm flake graphite muaj li ntawm 3 lab txheej ntawm graphene, thiab qhov zoo ntawm graphene tuaj yeem pom. Txhawm rau siv piv txwv pom, cov lus peb sau rau ntawm daim ntawv nrog cwj mem muaj ntau lossis kaum txhiab txheej ntawm graphite. ene.
Txoj kev npaj graphene los ntawm flake graphite yog yooj yim, nrog ob peb qhov tsis zoo thiab cov pa oxygen, cov graphene ntau, qhov loj me, thiab tus nqi qis, thiab tsim nyog rau kev tsim khoom lag luam loj.
